(a) The electrostatic force (not energy) of attraction between two oppositely charged objects is given by the equation F = k (Q₁Q₂/d²) where k = 8.99⨉10⁹N-m²/C², Q₁ and Q₂ are the charges of the two objects in Coulombs, and d is the distance separating the two objects in meters. What is the electrostatic force of attraction (in Newtons) between an electron and a proton that are separated by 1⨉10² pm?
